Fast, Reliable Fence Installation Across Union City
Fence installation in Union City typically runs $3,500 to $9,000 for a standard residential job, with vinyl and aluminum on the higher end and wood or chain link on the lower. We’re in Union City every week, and we know what these fences live through: bay winds off the salt flats, clay and fill soil that shifts, and 1960s tract lots that rarely have a perfectly square line. That’s why we quote in writing, pull the permit, and don’t hide behind a call center. Call (877) 610-1318 and you’ll get Tom or one of his sons, not a menu.
Union City sits at the southern edge of San Francisco Bay, and the flatland neighborhoods, from Decoto out to Alvarado, were built on former salt pond margins and tidal fill. That soil moves. A fence post set twenty inches deep in Fremont’s hills is one thing; a fence post set the same depth in Union City’s bay mud is another thing entirely. We order the right concrete depth for the ground you actually have, not the ground we wish you had.
Why Barrett & Sons Construction Is Union City’s Preferred Fence Installation Company
Tom Barrett started this company in 1998, and he still puts his name on the truck, his phone number on the contract, and his address on the permit. His sons run the crews. When you hire Barrett & Sons for Fence Installation in Union City, the person you shake hands with is the person whose name is on the work.
We’ve built fences on Medallion Avenue, on Regents Boulevard, on the quiet courts off Dyer Street. Homeowners call us because their last contractor wouldn’t pull a permit on a property line fence, or because they got a phone quote from an outfit and a different price at the door. Our price changes arrive as written change orders, before a single post goes in. Every eligible job gets permits pulled and inspections signed. If it’s not right, Tom comes back. That’s the 90-Day Done Right Promise, and it’s written on every contract.
There’s no dispatch board sending strangers to Union City. Tom lives twenty minutes away. If something’s wrong with your gate latch in November, he wants to know about it.
Our Fence Installation Services in Union City
Wood Fence
Wood fences are the workhorse of Union City’s older tracts. Cedar and redwood hold up well here if they’re set on galvanized posts, but the bay moisture will rot a post set directly in the fill soil within a decade. We use pressure-treated posts, concrete footings, and stainless hardware, and we run boards tight enough to give you privacy without buckling when the delta winds push through. A standard cedar privacy fence in Union City runs $3,500 to $7,500 depending on footage and gate count.

Chain Link Fence
For side yards, pool enclosures, or rental properties in the Alvarado district, chain link is the sensible choice. It’s the most affordable option, handles Union City’s shifting clay without cracking, and requires almost no maintenance. We install galvanized and vinyl-coated chain link with terminal posts set in a full concrete collar, which you need here more than in neighboring hillside suburbs. Typical Union City chain link runs $3,500 to $6,500.

Vinyl Fence
Vinyl is clean, bright, and won’t rot, which matters when your back fence faces open exposure off the bay. The wind picks up hard in the flatlands, so we set posts deeper and space them closer than what some out-of-area contractors will bother with. White and tan vinyl privacy fencing is popular in the newer subdivisions near Ponderosa Park. Expect $4,000 to $9,000 in Union City.

Aluminum Fence
Aluminum fencing works well around pools, on low front yards, anywhere you want the look of wrought iron without watching it rust in the marine air. In Union City the salt fog off the bay will eat cheap steel in a few seasons. We use powder-coated aluminum, and we set it with concrete backfill deep enough to anchor it in the soft ground. Aluminum fence installation runs $4,000 to $10,000 here.

Trusted Brands We Service in Union City
We don’t install mystery materials off a van. On paver work we carry Techo-Bloc and Cambridge Pavers, products you can look up, with published specs and factory warranties. On fence runs along driveways and walkways, we’ll often tie into existing hardscape with Quikrete mixes or Oldcastle bases where the gate posts meet concrete. If a gate post needs to sit in a paver driveway, we do both trades under one crew and one contract, no finger-pointing between subs. That’s why our fence customers in Union City often come back for Driveway & Pavers in Union City when they replace the cracked slab the next season.
Common Fence Installation Problems We See in Union City Homes
- Leaning posts in bay fill. Union City’s flatlands sit on liquefaction-prone soil, and shallow-set posts start to drift within months. We’re used to spec’ing deeper concrete collars and, on long runs, wider footings. A leaning fence posted in Fremont’s firmer ground might just need re-setting; in Union City it often needs a total re-post.
- Rot where fence meets lawn irrigation. Half the Union City homes we visit have sprinkler heads firing directly into fence pickets. Over years, that constant moisture rots the bottom rail. We’ll check your irrigation spray pattern and raise or redirect heads while we’re on site.
- Property line disputes with older lots. The Decoto and Alvarado districts have pre-WWII parcels with lines that don’t always match what’s on the assessor map. Before we dig, we recommend a survey if the neighbor’s fence sits close to the line. Permits are easier when the line is documented.
- Wind-broken panels from delta gusts. Union City gets hit on all four sides, and old wood fences with dry-rot snap. If you’re replacing a wind-damaged run, we’ll recommend steel posts even on a wood fence. The visual stays the same; the frame stops folding.
Pricing for Fence Installation in Union City, CA
Fence installation in Union City runs $3,500 to $9,000 for most homes. Wood and chain link sit on the low end, vinyl mid-range, aluminum and iron on the high end. What moves the number most is footage, gate count, access (some Alvarado backyards are tight), and what we find underground. If the existing posts were set shallow in bay fill and never concreted, the re-set isn’t a small patch job, it’s dig and re-pour.
We don’t give prices that balloon at the end. Every scope, every allowance, every change order is in writing before work proceeds. Call (877) 610-1318 for a free estimate. Tom will walk the line with you and tell you what it actually costs, in Union City, on your street.

In some ways, yes. Soil conditions here mean deeper footings and more concrete than you’d need in Fremont’s hillside tracts. That’s an honest difference, and it’s why our quotes for Union City don’t look like copy-pasted pricing from a Fremont page.
Every eligible fence job gets permits pulled and inspections signed. Union City’s building department requires it on most property line and height-over-six-foot fences.

Fences, Gates, and the Backyard That Follows
Most fence work in Union City is just the first project. Once the property line is set and the old fence is gone, people start asking about the side yard, the driveway, the ADU for the grandkids. We do all of it. If the fence is part of a bigger plan for Home Additions & ADU in Union City, talk to Tom early. We’ll coordinate the fence and the addition so the property line and setbacks line up, and you’re not re-doing fence work after the foundation goes in.
Whether it’s a fifty-foot backyard privacy fence in the Decoto district or a full property perimeter in the newer subdivisions, we’ll look at your lot, the soil, the wind, the neighbor’s irrigation, and the survey, then put a number in writing you can trust. Call (877) 610-1318 for your free estimate. Free Second Opinion on any written estimate, too. If someone else already quoted you, let Tom read it. He’ll tell you straight whether the price holds or whether you’re about to get surprised at the door.
